LS inverter classification

When the line power supply exceeds the driver's kV-A rating by 10 times, add a line reactor. A 3% impedance line reactor should be used to reduce power line transients caused by capacitor switching, line notching, DC bus overvoltage tripping, and inverter overcurrent and overvoltage conditions. Line...

1. The power value of the inverter is the most suitable for the power value of the motor, so as to facilitate the operation of the inverter at a high power value. 2. When the power classification of the inverter is not the same as the power classification of the motor, the power of the inverter should be as much as possible.

1. Power off the inverter and power it back on; 2. Press the FN button on BOP-2; 3. After the digital input 3, the default setting of 3 is reset to the problem; 4. Press the P button or power off, in the case of no problem; ...

How LS Contactor Works: Generally, after the contactor coil is energized, the entire coil current will generate a magnetic field, which will make the core inside have electromagnetic attraction to attract the core, and let their communication contactor point action normally closed contact disconnect, or close, which ...

LS inverter, the full name of LS AC inverter governor, converts direct current into alternating current by providing a variety of use configurations, and controls the speed of the motor by changing the voltage and frequency of the general power input to meet different industrial needs, so as to complete the energy saving and environmental protection of the automation system. ...

There are many functional parameters of the inverter, and there are generally dozens or even hundreds of parameters for users to choose. In practice, it is not necessary to set and debug every parameter, and most of them only need to use the factory setting value. However, some parameters are very closely related to the application of practice, and some of them are still ...

(1) The cooperation between the circuit breaker and the circuit breaker should consider the instantaneous trip device action value of the superior circuit breaker, which should be greater than the maximum expected short-circuit current at the outlet end of the lower circuit breaker.

1. The inverter should not be installed on the equipment with a sensation, because the main circuit connection screw in the inverter is easy to loosen, and many inverters are damaged due to this reason. 2. Wiring problem: the input terminal of the inverter should be connected to a ...

Each type of servo motor has additional torque, maximum torque and servo motor inertia and other parameters in the standard items, each parameter and load torque and load inertia must have a relevant connection, the output torque of the servo motor should meet the requirements of the movement conditions of the load organization, such as the speed of the acceleration ...

Power refers to the amount of work done by an object in a unit of time, i.e., power is a physical quantity that depicts how fast or slow work is done. The amount of work is constant, and the shorter the moment, the greater the power value. The formula for finding power is power = work/moment. Power is a physical quantity that characterizes the degree of work done fast or slow. Units made in the hour ...

(1) Tripping LS electric molded case circuit breaker basically involves the tripping unit in the process of practical application, and the tripping is generally a tripping method of thermomagnetic tripping or electronic tripping. In the process of practical application, if it is a ...

1. Look: The normal operation of the motor has a great relationship with the surrounding environment. Therefore, during the daily inspection, check the water leakage and dripping conditions around the motor (which will cause the low insulation of the motor to form breakdown and burn out), and check whether the peripheral of the motor has affected its ventilation and heat dissipation ring.

1. Auxiliary contact: the contact mechanically linked with the main circuit of the circuit breaker and the closing mechanism is mainly used for the display of the circuit breaker and the closing status, and is connected to the control circuit of the circuit breaker through the opening and closing of the circuit breaker to control or interlock its related electrical appliances. For example, output to signal lights, relays, etc.

An important difference between servo and frequency conversion is that frequency conversion can be without encoder, while servo must have an encoder for electronic commutation. 1. What the two have in common: The skill of communication servo itself is the learning and application of ...

In the course of regularly checking the variable-frequency drive (VFD) of the tensile testing machine, we can visually check the operating status directly from the outside. (1) The ambient temperature is normal, and it is required to be between -10°C and +40 ...

Brake unit: The function of the braking unit is to turn on the energy-dissipating circuit when the voltage Ud of the DC circuit exceeds the specified limit (such as 660V or 710V), so that the DC circuit can release energy by thermal energy after passing through the braking resistor. The braking unit can be divided into built-in and external, the former is ...

high-power Although some inverters are fan type inverters, but it is a low-power fan inverter, such an inverter does not have the effect of energy saving, and it is necessary to achieve energy saving must be a high-power inverter, in addition to the high-power fan inverter, it is necessary to meet its ...

Frequency conversion speed regulation motor is generally selected 4-level motor, the fundamental frequency operation point is designed at 50Hz, the frequency of 0-50Hz (speed 0-1480r/min) scale of the motor for constant torque operation, frequency 50-100Hz (speed 1480-2800r/min) scale of the motor for constant power operation, the entire speed regulation scale of (0 ...

　　The main functions and functions of PLC: 1. For sequential control: sequential control is based on the current and pre-historical situation of the input switch, and produces the required switching output, so that the system can operate in a certain order. ...
